I Application filed February 19, 1908. Serial No. 416,795.

-Be it known that L'VVILLIA'M B. HUGHES,

' a citizen of the United States, residing in the city of Cleveland,county of Cuyahoga, and State of Ohio, have inventedcertain Improvementsin Gas-Producers, of which the following is a specification.

This invention is a gas producer having improvements'designed forproviding in creased efliciency and producing a gas free from tar, bycombining air and steam or vapor with and effecting combustion of thehydrocarbons evolved in the production of the gas.

In the. referred modeof operation, the fuel is through the top of theproducer, the bulk ofithe air and steam isintroduced through the bottom,the burning fuel ismechanically agitated, air and steam are introducedthrough the to of the producer for combination with the iydrocarbonsdistilled from thebur-ning fuel, and the. gaseous products of,eiimbnstio1i are'discharged by a Water cooledconduit havingits inletembedded in thefuel at. a region} of high temperature through which'thetarry matter distilled from the coal athigherxregions of lowertemperature and combined with air and .steam must pass in order toescape, whereby matter passin through the gas outlet is subcompletegasification.

.In the accompanyin 1s a vertical sectional View of a gas producerembodying theinvent ion, and Fig. 2 is a plan view thereof.

The producer illustrated has the station ary cover 1 supported by thebeams 2, the stationary base 3 sup orted by the beams 4;, and therev'oluble bo y 5 carried by Wheels 6 which run on the circular track 7on the base.

The cover 8 depending in the corresponding water,

channel 9 on the body to seal the top, is procentrally therein andextends into, the body to a level below the contemplated top ofthe fuelbed in" a region of comparatively high temperatures during operation:

The lower part 'of'the-tube 10,fro1n the bottom to a point above thecoven-iscomosed of concentric shells v 1O forming a drawings, Figure 11, having thecylindrical apron 11 extending to a point near the bottomof the chamber and the vapor being discharged by an outlet 12 at the topthereof.

A pipe 13, fixedto the cover, provides a passage extending therethroughfor the introduction of air into the top. of the are ducer above thebody offuel, and. a smaller pipe 14 extends intothe pipe 13 for theintroduction of steam pr vapor.

A poker 15, having trunnions l6 ournaled in bearings 17 carried'by thecover, extends into the body to a point near or below the inlet to thegas tube,fand has its top con nected-by a link 18-with a revolving crankshaft 19, the poker being oscillated thereby in a plane parallel ti) andclearing the gas tube so as to slice the .fuel introdueedto therevolving body through. the ports 20.

The body is revolved through circular rack 2101i a spider 22, which isfixed to-the body and carries bearings 23 for the Wheels 6, the rackbeing'engaged by a pinion 24- tixed to a shaft 25 revolving in bearin s26 Carried by. the column 27. The shaft. is revolved by the pinion. 28fixed thereon, the pinion 29 engaging the pinion 28, the spur gear 30fixed to the pinion 29, the pinion 31' engaging the spur gear 30, thespur gear 32 fixed to the. pinion 31, and the pinion .32 engaging thegear 32 and fixed on the driving shaft 32". The pitman 38, having theeccentric connection 34: with the spur gear 32,

oscillates the pawl mechanism 35 and revolves the ratchet Wheel 36 fixedto the crank shaft bywhich the poker is oscillated.

The body has the cylindrical apron 37, d epending in the correspondingwater channel 38 on the base, and the depending cylindrical apron 39,forming part of an ash hopper, inside of the channel.

The cooling and scaling functions may be eifected by Water flowingthrough the pi e 11 into the chamber 10", thence by the tube 12 into thebasin like cover 1, thence by the spout 1" into the channel 9overflowing into the pocket 9, thence by the pipe 40 into the channel 38overflowing into the pocket 38, and thence escaping by the pipe 41.

' The base is provided with the blast pipe 42 (fed by the air pipe 42and the steam pipe 42") terminating in the hooded dome 43 centrallydisposed in theashhopper'of.

the body and carried by the spider 44 on the 'vertical'shaft 45supported in the blast pipe.

' nea-th the-body, is the basin or Conc ave table- 46 for sustaining theashes in the'body hopper, a radially adjustable b21114 carried-by thebase breaking up the column and throw ingoff the ashes into the hopper 3of the base when either the body or the table is revolved.

To, permit the dome and tableto resolve,

if desired, the spindle 45 may be revolubly supported on a step bearing45', and to hold such, revoluble parts against revolution pin 4-?"carried by the base is movable longitudh nally into engagement With thetable... The

table nay be revolved in sny known manner; as through the friction ofthe ashes on'-re- 'volving the body or-When thebody is stationary byhand if desired.

. Partiouliirly in using [bituminous coal, with its tendencyto cake andexpand, it is essential for satisfactory results to agitate.

and break up. the upperstrata. whi'oh' eannot be satisfactorily donemanual'y, end in the present mode ofoperation a. meohanically operatedpoker is so placed and used as to effectually breakup the distillingcoal. as the body revolves ithout"interference with the gastubeoentrally disposed mid-extend ing into the-revolving body of fuel sothat matter escaping therethrough must pass through a body ofincandescent coal; the combination of the-tarry matter, air. and vaporin t'he'top of t e producer being furthered by passing hrough suchincandescent fuel and theactions aided by theopemtion of the pokerHaving described my invention, I'ola-hn: 1.
